WHEEL-VEHICLE.

Specification of Letters Patent No. 19,088, dated January 12, 1858.

T 0 all whom it may concern.

Be it known that I, JOHN HEIDEN, of the city, county, and State of NewYork, have invented new and useful Improvement in heel vehicles; and Ido hereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the accompanyingdrawings, making a part of this specification, in which- Figure 1 is aplan or top view of my improvement. Fig. 2 is a longitudinal centralsection of the same. Fig. 8 is a back view of the same. Fig. i is afront view of the same. Similar letters of reference indicate like partsin all the figures.

This invention relates to an improvement in wheel-vehicles, whereby thesame may be turned (by a simple means) within a small space.

The invention consists in having both the front and back wheels attachedto levers, and having the levers of both pairs of wheels connected byrods in such a way (hereinafter described) that both the front and backpairs of wheels may, as the shafts or draft-pole is turned, be crampedor turned simultaneously in opposite directions and thereby effect thedesired purpose.

To enable those skilled in the art to fully understand and construct myinvention, I will proceed to describe it.

A, B, represent two parallel bars to the underside of each of which aspring C is attached, and to the center of each spring a bar or bolsterI) is attached. To the ends of the bolsters D, curved bars E aresecured, to which bars the bed F, and consequently the body of the"ehicle, is attached. The springs C are flat strips of steel, havingeach end attached to itsrespective bar, or semielliptical-leaved springsmay be used. The bars A, B, are placed at the same distance apart as thefront and back axles of all vehicles; and said bars in fact formportions of the axles of the vehicle, for the levers to which the wheelsare attached are pivoted to the bars A, B. The back wheels G, G, areattached to levers H, H, pivoted to the ends of the bar B, as shown at(a, a.) The inner ends of the two levers H, H, are connected to the endsof a lever I, by means of pins (61",) passing through the ends of thelever I, and fitting in slots in the inner ends of levers H, H. Thecenter of the lever I, is pivoted to the center of bar B, as shown at(6); see more particularly Figs. 1 and 3.

The front wheels J, J, are each attached to a lever K, which levers arepivoted to the ends of the bar A, as shown at (c, c). The inner ends ofthe levers K, K, are connected to levers L, L, which are pivoted to barA, at ((Z, d), the levers K, K, being con nected to levers L, L, bymeans of pins (6, e), which are attached to the levers L, L, and fit inslots (f) in the inner ends of the levers K, K. The inner ends of thelevers L, L, are connected to the ends of a lever M, by means of pins(g) which are attached to the ends of said lever M, and fit in slots(72.) in the inner ends of the levers L, L. The lever M is pivoted atits center to the bar A, as shown at (6*). The draftpole or shafts areattached to the lever M, and the ends of the levers M, I, are connectedby rods N, N.

From the above description it will be seen that as the draft pole orshafts are turned, the front and back wheels will be cramped or turnedsimultaneously in opposite direc: tions as shown clearly in Fig. 1, andboth pairs of wheels will consequently be so placed as to run on or overshort curves. thereby causing the vehicle to turn within a small space.The movement of the two pairs of wheels in reverse directions is due tothe additional levers L, L, on the bar A.

I would remark that the bars A, B, and the levers that are attached tothem, and also the connecting rods N, N, will be constructed of metal,at least this will probably be the material used. I would also remarkthat the levers K, K, to which the front wheels are attached, passthrough loops 0, O, which are attached to the bar A, and serve as checksor stops to control the length of the vibration or movement of saidlevers and their wheels J, J.

I am aware that vehicles have previously been constructed so that theirfront and back wheels could move or turn simultaneously as herein shown.But I am not aware that the particular means employed for effecting thepurpose as herein shown has ever been employed. The devices hithertoemployed for such purposes, so far as I am aware, have been complicated,their operation attended with considerable friction, and the movement ofthe wheels comparatively restricted, cross levers being employed toconnect the two pairs of wheels.

I do not claim, broadly, connecting the front and back wheels of avehicle so that both pairs of Wheels may be cramped or M, H, H, and I,which are pivoted respecturned simultaneously for the purposespecitively to the bars A, B, and connected by the 10 fied. But rods N,N, substantially as and for the pur- Having thus described my invention,What pose set forth. 5 I claim as new, and desire to secure by Let- J.HEIDEN.

Attaching the front and back Wheels J, J, W. TUsoH, G, G, to theirrespective levers K, K, L, L, W. HAUFF.
